Class: l3dprojector

a projector allows textures to be projected on models, orthogonally and perspectively. There is a special texture type that can fix backprojection errors for perpective projection, but shouldnt be used on orthogonal, or if no errors with normal textures appear.

• fov
• frontplane
• new
• textureid

new (string name,l3dlayerid layer)

returns: (l3dprojector)

creates new projector

activate (l3dprojector,int id)

returns: ()

adds projector to the active list with given id (0-31)

aspect (l3dprojector,[float])

returns: (float)

returns or sets projection aspect ratio = width/height

attenuate (l3dprojector,[boolean])

returns: (boolean)

returns or sets attenuation, this is quite heavy effect but will perform a per pixel distance attenuation that causes the projector to fade out towards its backplane.

backplane (l3dprojector,[float])

returns: (float)

returns or sets projection backplane distance

blend (l3dprojector,[blendmode])

returns: (blendmode)

returns or sets blendmode of projector

deactivate (l3dprojector)

returns: ()

removes projector from active list

fov (l3dprojector,[float])

returns: (float)

returns or sets projection fov, when negative it will be orthogonal projection with abs(fov) rectangular size

frontplane (l3dprojector,[float])

returns: (float)

returns or sets projection frontplane distance

textureid (l3dprojector,[texture])

returns: (texture)

returns or sets projected texture
